Effects of some environmental factors on the fecundity of Tilapia species (Family Cichlidae) in Kigera Reservoir, New Bussa

The effects of some environmental factors on the fecundity of Tilapia species (Family Cichilidae) was carried out at the Kigera dam. Four Tilapia species caught were Tilapia zilli, Hemichromis fasciatus, Sarotherodon galilaeus and Oreochromis niloticus while the environmental factors considered were water temperature, Dissolved Oxygen, pH value, level of rainfall and rate of sunshine and range of time. 43 fish comprising of 25 male with (58.1%) and 18 females having (41.9%) were studied with 74.42% been sexually matured. Both high levels of rainfall and dissolved oxygen favoured fecundity. The spawning peak occurred in (July), environmental factors monitored indicated that dissolved oxygen ranges from 3.7 to 4.45mg/lit rainfall ranges from (34.90mm to 237.80mm) sunshine ranges from (5hrs-8hrs) and pH ranges from (7.35-7.45). The spawning of these species in their natural or hatchery condition is therefore best achieved during the peak of raining season

Effects of substituting fish meal with grasshopper meal on growth and food utilization of the Nile Tilapia, Oreochromis niloticus fingerlings

The effects of substituting fish meal with grasshopper meal in fish diets on the growth, food utilization and survival of the Nile tilapia, Oreochromis niloticus (mean weight = 40.1g) were investigated. The results show that the best growth and food utilization were recorded in the fingerlings fed in the 10% grasshopper meal and 30% fish meal while the poorest growth and food utilization indexes were recorded with the 25% grasshopper meal and 15% fish meal. In general, at 10% inclusion, the fingerlings performed even better than the control (40% fishmeal and no grasshopper meal)

Estrategias de arranque de biofiltros orgánicos para el tratamiento de corrientes gaseosas contaminadas con compuestos de azufre

[ES]El disulfuro de carbono (CS2) y el sulfuro de hidrógeno (H2S) son gases especialmente tóxicos presentes en una gran cantidad de emisiones gaseosas industriales, principalmente en la producción de fibras de rayón a partir de celulosa en el caso del CS2, y en la industria petroquímica en el caso del H2S. La legislación vigente en cuanto a las emisiones de estos compuestos se refiere hace que su tratamiento sea, en muchos casos, necesario. La biofiltración como tecnología para el tratamiento de corrientes gaseosas contaminadas se ha convertido en los últimos años en una alternativa a los tratamientos físico-químicos empleados hasta la fecha. Sin embargo, uno de los principales obstáculos a la hora de la implantación de este tratamiento biológico a escala industrial es la duración del periodo de aclimatación de la biomasa encargada de degradar los contaminantes, que en función del compuesto a tratar puede resultar demasiado largo para la aplicación comercial de esta tecnología. El presente trabajo se centra en el estudio de estos periodos de arranque y aclimatación, especialmente lentos en el caso del CS2, y propone una estrategia de arranque basada en la reutilización de biomasa capaz de degradar los compuestos de interés, almacenada tras usos anteriores, que permite reducir el tiempo necesario para alcanzar eficacias de eliminación elevadas. Paralelamente, se ha concluido que paradas de corta duración no afectan de manera importante a la operación del sistema.

Estimation of growth and financial analysis through the application of Ipil ipil (Leucaena leucocephala) leaf meal as supplements to soybean and fish meal in the diet of juvenile monosex tilapia (Oreochromis niloticus)

Among plant protein ingredients,ipil ipil (Leucaena leucocephala) leafmeal (ILLM) is considered the most nutritive plant protein source after soybean meal in aquatic feeds. That was proven in a 21-day experiment conducted to assess the response of juvenile Monosex Nile tilapia Oreochromis niloticus with four iso-nitrogenous formulated diets: One control diet was formulated based on fishmeal, one on soybean meal and one on rice bran, ipil ipil leafmeal was also included in experimental diets.

Application of ipil- ipil leaf meal (IILM) as feed Ingredient for Monosex tilapia fry (oreochronis niioticus) : In terms of growth and economics

The Ipil-ipil (Leucaena leucocephal) leaf analyzed for crude protein (CP), fat, crude fibre (CF), ash content, moisture content and nitrogen free extract (NFE). The CP 23± 0.12 % , fat 8 ± 0.11 %, CF 18 ± 0.15 % , ash 10 ± 0.13 %, moisture 14. ± .16% and NFE 29.± 1.10 % were recorded. A twenty one days experiment was conduced to assess the response of juvenile monosex tilapia with different iso-nitrogenous formulated diets for find out the feasibility study of using ipil-ipil leaf meals as feed ingredient for juvenile tilapia. Three experimental diets were formulated by using fish meal, soybean meal, rice bran and ipil ipil leaf meal. One control diet was formulated by using fish meal, soybean meal and rice bran. Considering the high demand, limited availability of fish meal and soybean meal, ipil ipil leaf meal was incorporated in juvenile tilapia feed. Among plant protein ingredients ipil ipil leaf meal was considered as the most nutritive plant protein source after soybean meal. However, high concentration of toxic element limited the incorporation level of ipil ipil leaf meal in fish feed. Use of 15 % ipil ipil leaf meal in fish feed was more significant from the view of growth performance and economics. The higher Absolute Growth was 1119.26 gm, higher Specific Growth Rate was 6.52% /day higher Feed Conversion Efficiency was 41.23% , higher Protein Efficiency Ratio was 1.178 and higher Average Daily Growth rate was 14.00% recorded in diet-4 ( which contained 15% IILM). The lower Feed Conversion Ratio 2.42 and lower cost for per unit production 34.65 taka/kg were recorded in diet-4. The higher cost for per unit fish production 45.6 tk./kg was recorded for diet-1 where no ipil ipil leaf meal.. The results suggest that tree legumes Ipil-ipil (Leucaena leucocephal) leaf has potential and excellent source of feed ingredients as protein supplements for juvenile monosex

Los fenómenos de marea roja y toxicidad de moluscos bivalvos en el Mar Argentino

Two unusual blooms of dinoflagellates appeared in the Argentine Continental Shelf in spring/summer period of 1980 and 1981, but these differed, one from the other. The first was an intense red-tide with which were associated no signs of toxicity, whereas the second, although; not showing special coloration, was associated with (and doubtless the cause of) intense toxicity in bivalves of the Gulfs of San Matías and San José and of the shelf waters off Península Valdés; the death of two fishermen was atributed to the latter. The first bloom developed as an unusual surface concentration of the predatory dinoflagellate Noctiluca scintillans. It was supposed that this concentration was produced by a particular combination of processes of circulation of water masses. The second bloom was characterizaed by high concentrations of Gonyalax excavata. Investigations at the time determined that toxins in molluscs of the area correasponded to what is called "paralytic shellfish poison". The bloom of G. excavata was associated with a front between well mixed and well stratified water masses. The maximum toxicity centre occured in the mussel bank "Constanza" (42°23'27"S and 62°45'66"W) which coincides with the front referred to above. (PDF contains 93 pages)

Changes in feeding biology of Nile tilapia, Oreochromis niloticus (L.), after invasion of water hyacinth, Eichhornia crassipes (Mart.) Solms, in Lake Victoria, Kenya

Oreochrimis niloticus (L.) was introduced to Lake victoria in the 1950s. It remained relatively uncommon in catches until 1965, when the numbers began to increase dramatically. It is now the third most important commercial fish species after the Nile perch, Lates niloticus (L.) and Rastrineobola argentea (Pellegrin). Oreochromis niloticus is considered a herbivore, feeding mostly on algae and plant material. The diet now appears to be more diversified , with insects, fish, algae and plant materials all being important food items. Fish smaller than 5 cm TL have a diverse diet but there is a decline in the importance of zooplankton, the preferred food item of small fish, as fish get larger. The shift in diet could be due to changes which have occurred in the lake. Water hyacinth, Eichhornia crassipes (Mart.) Solms, which harbours numerous insects in its root balls, now has extensively coverage over the lake. The native fish species which preyed on these insects (e.g. haplochromines) have largely been eliminated and O. niloticus could be filling niches previously occupied by these cichlids and non cichlid fishes. The change in diet could also be related to food availability and abundance where the fish is feeding on the most readily available food items.

Estudio de catalizadores basados en zeolitas HZSM-5 sometidas a tratamiento in situ con vapor de agua para la transformación de 1-buteno a propileno

El propileno es un monómero muy versátil y es la materia prima para una amplia gama de polímeros, intermedios y productos químicos. Esta versatilidad se debe a su estructura química: al igual que el etileno, el propileno contiene un doble enlace carbono - carbono, pero a diferencia de éste, el propileno contiene también un grupo metil - alílico (un grupo metilo adyacente a un doble enlace), otorgando a los químicos, diseñadores catalíticos e ingenieros dos distintas alternativas para llevar a cabo las trasformaciones químicas, por lo que son más numerosos los derivados del propilen o que del etileno (Plotkin, 2005).

El VIH: el origen, la patología y el tratamiento

The HIV (Human Immunodeficiency Virus) is a very important disease in the world, with approximately 35 million people infected. In this study we have tried to expose the main characters of the virus, explaining the disease and the illness associated to the HIV. Besides, we have explained the antiretroviral treatments that are the most important weapon against the HIV. However, any of these treatments do not eliminate the HIV in the human body. For this reason, we have been looking for the new treatments and researches that have been development in the last years, including vaccines and genetic resistance. In addition, we have described the situation of the SIV (Simian Immunodeficiency Virus) in Africa, because it is the origin of the disease. The prevalence of the virus in primates population is something that have being studied for the last years, because it could be a new threat to the human population. Finally, we have proposed the researches lines that seems to be more effective and the ones that, in a future, could eliminate the virus in the human body.
